Application-filed February 18, 1914-. Serial No. 819,304;

Be it knownthatv I, HERMAN F. BALL, of the borough. of Manhattan, in the city, county, and State of New York, have 1nvented a certain newand useful Im rovement in Trucks for Railroad-Vehic es, of which improvement the following is a sp ifi ti n- My invention, while more particularlyv relating to'leading trucks for locomotive engines, 1s equally ap licable'in railroadv rollsescriptions and its/object is to provide a four wheeled truck, of

the swin ;or lateral motion"type,'which shall be 0 simple and inexpensive construction, of increased lateral stability relatively to those ordinarily heretofore used, and in which the removal. and replacement of either pair of wheels may be readily and expeditiously efiec'ted when desired.

The improvement claimed is hereinafter fully set forth.

In the accompan ing drawings: Figure 1 is a view, the left and half of which is a side elevation, and the right hand half, a vertical longitudinal central section, of a truck embodying my invention; Fig. 2, a half plan view of the samefFig. 3, a vertical transverse section, taken in the central plane of one of the axles; and, Fig. 4, a.

view, the left hand half of which is an end elevation, and the right hand half, a vertical transverse central section- My invention is herein exemplified in a four wheeled leading engine truck, the frame of which is of the following construction.

Two side bars, 1, which are of rectangular section, and made of commercial iron or steel, extend along the sides'and top of the truck, andare connected one to the other, at and near their ends, by transversely extend ing pedestal transoms, 1 which are of invcrted U section and have pairs of integral pedestal jaws, 1*, formed on their ends. The pedestal transoms are secured detachably horizontal flanges on the tops of the pedestal jaws and fitted with proper nuts. The side bars are likewise connected, in and adjoining the central transverse plane of the truck, by a swing bearing frame, 1, which is secured, at its ends, to theside bars, by

bolts,-1, and nuts fitted thereon. I a

The truck wheels, 2, are secured, in the usual manner, on the ends of: the truck axles,

2, the ournals, 2", of which, rotate in bearings, 2F, fitted in axle boxes, 2, each of which is adapted to traverse vertically be:

tween themembers-of one of the pairs of pedestal jaws, 1". The truck frame is, in this instance shown as supported, on the axle boxes through the intermediation of plate springs, 6, the central bands, 6, of

which, are fitted in seats on the lower side of the swing bearing frames, 1", and which are coupled, at their ends, by links, 6", to

pairs of equalizers, 7, the ends of which bear on seats on' the tops of the axle boxes, 2. The spring arrangement does not form part of my present invention, and any other known and preferred design may be substituted for the ordinary construction herein shown and described.

The two inner edestal jaws, 1", on each side of the truck rame, are connected by a tie bar, 3, which, instead of extending to the outer pedestal jaws, as in ordinary practice, is turned upwardly at its ends, and secured to the inner pedestal jaws by bolts, 3, and nuts, and, as shown in Figs. 2, 3, and 4, the tie bars, 3, are located in planes onthe inner sides of, and entirely clear of, the axle boxes. The inner and outer jawsof each pedestal are connected by a pedestal binder bolt,'3", which also passes through the upwardly extending end portion of the adjacent tie bar, 3, and additionally secures it to the inner pedestal jaw, by a nut, 3, engaging a thread on the binder bolt, 8", and

bearing on the tie bar, 3.- The binder bolts are provided with nuts, 3, bearing on the outer pedestal jaws, and nuts, 3", bearing on the inner sides of the inner and outer jaws. By this construction, the axle box cellars, 2, may be removed and replaced whenever required, without interference by the tie bars, and it will also be seen that in order to enable either of the axles and its pair of wheels to be dropped, it is only necessary to remove the two binder bolts, 3, of its pedestals.

The capacity of lateral mot-ion of the truck frame and its axles and wheels, relatively to the main frame of the locomotive or car on which the truck is applied, is

pension illustrated does not, however, form I nectin the lower'ends of the pedestal jaws. pair, it will be obvious that a tie' of eac barconnected at its ends to the pedestal jaws would constitute the mechanical e uiv- 'alent of a binder bolt and may be su stituted therefor in the iscretion of the constructor.

'I claim as my invention and desire to secure by Letters Patent:

1. In a frame for arailroad truck, the combination of two side bars and two pedestal'transoms, said transoms havin pairs of edestal jaws formed integral wit their en s side bars, adjacent to the ends thereof.

2. In a frame 'for a, railroad truck, the combination of two side bars, two pedestal transoms having pairs of pedestal jaws formed inte al with their ends and bein secured at't eir ends to the sidebars, a

jacent to the ends thereof, and a transverse swing bearing frame secured at its'ends to the slde bars, intermediate of the pedestal transoms.

3. In a frame for a railroad truck,- the combination of two side bars, two pedestal transoms, having pairs of pedestal jaws formed integral with their ends and being each extendin middle transverse and being secured at their ends to the;

secured at their ends tothe side bars, ad-

jacent to the ends thereof, and two tie bars, longitudinally in a plane on the inner s1 es of the pedestal jaws, and secured at its ends to the pedestal jaws nearer the .middle transverse plane of the truck.

4.'In a frame for a railroad truck, the combination of two side bars, two pedestal transoms having pairs of pedestal jaws formed inte ml with their ends and being secured at t eir ends to the side bars, adjacent to the ends thereof, two tie bars each extending longitudinally in a plane on the inner sides of the pedestal jaws and secured at its ends to the pedestal jaws nearer the lane of the truck, and pedestal binder bolts, each connectin the members of a pair of pedestal jaws and also connecting a tie bar to one of said members.

5. In a railroad truck, the combination of two side bars, two pedestal transoms having pairs of edestal jaws formed integral with their en s and being secured at their ends to the side bars, adjacent to the ends thereof, two tie bars, each extendinglongitndi nally in a plane on the inner sides of the pedestal jaws, and secured at its ends to the pedestal jaws nearer the middle transverse lane of the truck, a transverse swing bearmg frame secured at its ends to the side bars, intermediate of the edestal transonus a swing beam suspende on said bearing frame, and axle boxes fitted in the several pairs of pedestal jaws.
